This invention relates to a method .of fixing rails for supporting heavy wheel-loads on iron, 'wooden or concret-e sleepers.

The object of the present'invention is to .5 provide an arrangement which is very simple to manufacture and to fix and ensures absolutely secure bearing 4of the rail on the sleeper; The fixing of the rails is to be effected by means of a sole plate and this In Sole plate is to have the peculiarity, that the fixing on the sleeper is independent of the fixing of the rail on the sole plate, so that therails may be released Without its being necessary tov release. the, plate from the sleeper. This feature islof particular importance for iron and for concrete sleepers and in the case of wooden sleepers has the advantage that the holes for the sleeper screws may be made beforehand and be impregnated feature of the sole plate is, that it has n o holes besides lthe holes for the coach screws for the wooden sleepers, so that there'will be no accumulation of water`or dirt under the plate which would tend to destroy the sleeper.

The invention consists substantially in this that a sole plate is used which lies flat on the sleeper, isp preferably madel by rolling :m and is provided with upwardly extending ribs,- projections or the like forthe reception of the screws holding the clips. For this purpose theribs or projections are provided with recesses, into'which the clip screws can be inserted. Preferably the recesses'should not extend right'through the sole' plate, the

ribs or projections providing the means for 1 surfacesthe bolt is prevented from turning.`

holding the clip screws.

In the accompanying drawing-two constructional forms of the. invention are shown by way of eXample, in Figs.. l and 2 in transverse section and plan-view,l as .applied toa wooden sleeper, and in 3 as applied to an ironsleeper. 'f

'u As will be seen from Fig. 1, the new fixing means consists of a sole-plateaI which is prowhen the sleeper is being treated. A further ferred form of the bolts in side elevation vided with ribs or projections I). The soleplates arefiXed on the wooden sleeper c by means of screws d. Between the ribs or projections balies the rail The rail is held down on the sole plate by means of clips h which are drawn down' tightly on the sole plate by means of the bolts f. The bolts j engage in the ribs b preferably by their heads beinginserted in suitable yrecesses in the ribs. Gauge adjusting members fare introduced as required between the ribs and the base of the rail.

The sidej f theribs b facing the rail is preferably slightly inclined tothe sole plate with the object of preventing the gauge adjusting members which rest against the ribs l f from slippingupwards.

On straight parts of the track the distance apart of the ribsv or projections b may be made such that it corresponds to the width ofthe rail base,.i n which'case no gauge adjusting' members are required. i

f The fixing bolts f are made in the form of T-headedbolts. The head is either rectangular or trapezoidal. Preferably the head a 1 of the bolts has a curved bearing surface as nshown in Figure 4. In the latter case the recesses in the ribs of the sole plate need only be very low so that the ribs themselves and the entire plate will be relatively low.

r-With this form of head the bolts are capable of tilting slightly in a direction parallel to the rail, the width of the recess at the top of theJ projections b being slightly greater than the diameter of the shank of the bolt so 'as to` enable thebolt to 'rock'.

Through the head bearing against straight f'The construction of the sole plate` is shown 95 in detail in FiguresI 5, 6 and 7.. The plate a is-provided with ribs?) which are inclined inwardsand these ribs arefprovided with recesses s, into which the heads z of the screw bolts fit. Figures 8` and 9 show a pre- 100 and -plan view, Figure 9Jshowing that the bolt heads are narrow, corresponding to the width of the ribsi v The clips h, ywhich are screwed down firmly on vtothe sole-plate by means of the bolts `f yand therebyffirmly hold the rails in position, bridgev over the ribs or projections I b. Their shape is shown in Figures l0 and 1l. Theupper part of the clips is somewhat narrower than thewidth of the feet y for ,facilitating the screwing together of the the clip bolts atthe correct kvarious parts and. in [Vorder to prevent the` upper part of the clips bearing against the ish plates or the fish bolts. 7

For providing a particularly good., wide" 'bearingsurface'for the feet of the clips on the base of the rail and the sole plate, when the clips' are held down by the bolts, the

dentally. At the ends of the -upper e ge the gaugeplates are provided with'small projecting parts The recess lying between 2o lthe said projections n serves for th reception of the clips so that the latter are pre- .vented from slipping sideways.

,For provlding means for adjustlng .the

'l u gauge, lthe gauge plates are made Aas usual 25 in several thicknesses. On the sides projections or lugs u may be provided (Figs. 15, 16 and 17), which engage `in the recesses in the ribs and lthereby prevent the gauge `lplatesfro'ln slipping out and lalso securing distance from -the base of the rail. I v

' The `gauge may also be adjusted by means of the yclips la., if the clips are provided, as shown'din dotted lines in Fig. 10 with downwardly. directed lugs o,y of a suitablewidth, which lie between the rail base and the ribs (cf. Fig. 3). e f l Whenthe new sole plate is to be fixed' on an iron sleeper the sole plate a, as there are 4u no sleeperi-screws, is made correspondingly narrower (cf.Fig. 3) and isy fixed-in vany suitable manner on the; ironsleeper c, preferably bylbeing welded on it.
